Test Credit Card Generator — Luhn-Valid Dummy Numbers
Generate Luhn-valid Visa, Mastercard, Amex, and Discover test card numbers with expiry and CVV for payment-form QA and fixtures. Not a real payment method.
How generation works
Pick a quantity (1–100), a card network (or random), a number format, whether the Luhn checksum should be valid or deliberately invalid, and whether to include a CVV. Expiry is always a random future date. Changing an option refreshes the list immediately. Copy all or download JSON, CSV, SQL, or TXT.

Test credit card FAQ
Sandbox prefixes, Luhn, and what this tool is not
Can these card numbers be charged?
No. They are dummy strings for form QA and fixtures, built from publicly documented payment-processor sandbox prefixes. They are not tied to any bank account or cardholder.
Why do the numbers still pass Luhn?
Real payment forms validate the Luhn checksum before ever touching a processor. A test number needs a real checksum to exercise that code path — that's what the valid mode gives you.
What's the invalid checksum toggle for?
It flips the check digit so the number deliberately fails Luhn. Use it to confirm your validation actually rejects malformed card numbers, not just that it accepts good ones.
I searched for a fake credit card generator. Is this it?
If you need Luhn-valid dummy numbers for development, QA, and fixtures, yes. If you're looking for a way to make real purchases, this tool will not do that — and we will not add it.
